Most multi B supplements do not agree with me. There is a liquid multi B sold here on iherb (Life Time Liquid B) that is a lot more potent and doesn&#39;t bother me, but I like the convenience of these tablets. This is just a really nice B vitamin supplement that I would strongly recommend. Didn&#39;t realize I needed biotin, but I think it is a good part of this. I generally like Enzymatic Therapy products. I give the Biotin forte with zinc to my husband whose blood test showed low zinc levels.
